Allow for empty posts and empty topic body

Related to the issues described here https://meta.discourse.org/t/how-to-turn-off-body-seems-unclear-is-it-a-complete-sentence/318451

It seems that it is not possible to do the following;

  • create a new topic with an empty body message
  • create a post with an empty message

For the former, if you try to create a topic with an empty, or even single-character, body message, you get the error such as "Body seems unclear, is it a complete sentence?"

For the latter, if you try to create a post with an empty body, you get an error such as shown here; "Post can't be empty"

This is despite updating all known settings to reduce "entropy" values to the lowest possible values, and reducing the minimum post length as much as possible.

The settings already exist to control the post and topic body lengths. So it seems like they need to be modified to allow 0-length posts and topic body. I would think this would be a small change to the codebase, and it would be a lot more convenient to just have the existing settings modified to allow this rather than to require the server admin to write their own plugin to change minimum length values from 1 to 0.

Let me know what you think, thanks
